TV network fires Bear Grylls

The British television presenter began working with the network on TV series 'Man vs. Wild' - where he is challenged to survive in difficult climates - in 2006, but following problems getting him to work on two unannounced projects, they have decided to terminate their contract with him.

A representative for Discovery told The Hollywood Reporter: "Due to a continuing contractual dispute with Bear Grylls, Discovery has terminated all current productions with him."

His spokeswoman Heather Krug confirmed the news, but claims he is looking forward to working on other projects.

She said: "Bear's goal has always been to make life-empowering shows for his many fans around the globe, and he has taken great risks to bring Discovery such award-winning programming over seven seasons.

"Unfortunately, Bear and Discovery have not been able to come to mutual agreement on new programming, and he disagrees with Discovery's decision to terminate current productions.

"Bear has loved the 'Man vs. Wild' journey and looks forward to producing further cutting-edge content again soon for his loyal audience."

Celebrities including Jake Gyllenhaal and Ben Stiller have previously appeared on the series, which sees them work together to survive challenging environments.
